NumPy - Indexing and Slicing

What is wrong with this code snippet?

import numpy as np
arr = np.array([[1, 2], [3, 4]])
print(arr[2, 0])

APrints 3 correctly

BSyntaxError due to wrong brackets

CIndexError because row 2 does not exist

DPrints 1 correctly

Step-by-Step Solution

Solution:

Step 1: Check array shape and indexes
The array has 2 rows (index 0 and 1). Index 2 for row is out of range.
Step 2: Understand error type
Accessing arr[2, 0] causes an IndexError because row 2 does not exist.
Final Answer:
IndexError because row 2 does not exist -> Option C
Quick Check:
Row index 2 is invalid for 2-row array [OK]

Quick Trick: Check array shape before indexing to avoid errors [OK]
